Nonconcurrent baseline designs do not involve simultaneous data collection, and researchers should make this clear to avoid any confusion in the interpretation of the data. It is important to acknowledge that data collected during the pre-treatment phase of the study may be affected by other variables, which can make the results misleading. Therefore, researchers should take steps to control for extraneous variables and ensure that the data accurately reflect the true effects of the treatment.
